The stock X-type rear wheels do not have any adjustment for camber, but after an 8,800 mile road trip from AK across the mid US and back, my left inner rear wheel was quite worn. After I got back home, I replaced the lower suspension member (it was obviously worn at the end fitting rubbers), and because the wheel bearing was a little noisy, I replaced that also. Doing a little research, I found that the 2004 Volvo S40 upper control arms can used as replacements, and are available in an adjustable model. I am planning to go to a ‘zero’ camber to hopefully stop early wear on the rear tires. I don’t race or slalom the car. Have any other folks on the forum done this? Any obvious change in the way the car drives??
Haven’t done it but I have heard of the mod on another site.
